摘要：
We investigate the Rydberg wave packet dynamics of core-driven two-electron atoms with the density matrix formalism. The spontaneous emission of the core transition is included. We show how it modifies the dynamics of radial Rydberg wave packets, which are nondispersing, but slowly decaying in the absence of spontaneous emission. Although our considerations apply to all two-electron atoms, we focus on the experimentally convenient element calcium.
